Description

Metenkefalin belongs to the class of organic compounds known as oligopeptides. These are organic compounds containing a sequence of between three and ten alpha-amino acids joined by peptide bonds. The enkephalins are considered to be the primary endogenous ligands of the δ-opioid receptor, due to their high potency and selectivity for the site over the other endogenous opioids. Met-enkephalin is a pentapeptide with the amino acid sequence tyr-gly-gly-phe-met. Metenkefalin is a very strong basic compound (based on its pKa). Met-enkephalin has low bioavailability, is rapidly metabolized, and has a very short half-life (minutes). Met-enkephalin is found mainly in the adrenal medulla and throughout the central nervous system (CNS), including in the striatum, cerebral cortex, olfactory tubercle, hippocampus, septum, thalamus, and periaqueductal gray, as well as the dorsal horn of the spinal cord. Met-enkephalin was discovered and characterized by John Hughes, Hans Kosterlitz, et al. In 1975 after a search for endogenous ligands of the opioid receptors. It is through these receptors that met-enkephalin produces its opioid effects, such as analgesia and antidepressant-like effects. Met- and leu-enkephalin are metabolized by a variety of different enzymes, including aminopeptidase N (APN), neutral endopeptidase (NEP), dipeptidyl peptidase 3 (DPP3), carboxypeptidase A6 (CPA6), and angiotensin-converting enzyme (ACE). Proenkephalin A is first reduced by either one of two trypsin-like endopeptidase enzymes, prohormone convertase 1 (PC1) or prohormone convertase 2 (PC2); then, the resulting intermediates are further reduced by the enzyme carboxypeptidase E (CPE; previously known as enkephalin convertase (EC)). (2s)-2-{[(2s)-2-({2-[(2-{[(2s)-2-amino-1-hydroxy-3-(4-hydroxyphenyl)propylidene]amino}-1-hydroxyethylidene)amino]-1-hydroxyethylidene}amino)-1-hydroxy-3-phenylpropylidene]amino}-4-(methylsulfanyl)butanoic acid is found in Mytilus edulis. Proenkephalin A contains four sequences of met-enkephalin (at the following positions: 100–104; 107–111; 136–140; 210–214), And as a result, its cleavage generates four copies of met-enkephalin peptides at once.
